Reciprocably mounted in .-.anain frame, so asto thc'lisppezz 33- s risl N9. .851 6- and enter the guides 32', is a packer head 33, reciprocated by any suitable ineans, such, for instance, as pitinan 34L.

'Thus far, the construction is common and well known and needs no further description. c

A transverse gap 85, the purpose of which will be made to appear, exists betweenthe delivery end of hopper 31 and the receiving end of guides 32 and adjacent the delivery side of the hopper, I arrange a sta: tionary cutter bar 36, immediately above horizontal guides 37, a reciprocating cutter plate 38 being mounted in these guides so as to traverse the mouth or the hopper and cooperate with the cutter lade 36 upon each reciprocation of the packer plunger 33, plate 38 being connected by parts 39 with the packer head.

Arranged in the gap are transverse guideways 41, in which is supported a reciprocating plate 4 2, provided with two vertically-spaced arms 43, each of which carries a grooved wheel d4. wheel e iis arranged in a horizontal plane and is formed to have the binding wire pass around it, a small wheel l6 being arranged closely adjacent Wheel 44-, for a purpose which will appear.

Journaled in a vertical bar 50, or main plate, adjacent gap 35 and substantially in the same horizontal plane with each wheel 4%, is a shaft 51, which carries a cutter head 52, formed, in the present instance, with six circumfercntially-spaced radial cutters which are adapted to cooperate with the end of a stationary cutter plate 54:, secured to one face of bar 50.

Each shaft 51 also carries a holder head 55 which comprises six radial fingers A, B, D, E and F, which correspond to the six cutter fingers of the cutter head 52, the cutter fingers being' set slightly in advance of the lingers of the holder head 55. EA wear plate 56 is placed between bar and the holder head and the adjacent portion of each of the fingers of the holder head is grooved, as indicated at 57 (Fig. '17) to permit wire 45 to lie between the holder head finger and plate 56. 7

Head 55 is circumferentially grooved, as indicated at 58, so that a stripper finger 59 may be projected into said groove and-serve to strip portions ,of wire dti tro n head 55 in a manner Which will be described.

liar is nutchedat 6G and plate 56 This grooved notched at 61 to correspond with notch 53 of the cutter plate 54.

The initial end of wire lies between finger B (Fig. 19) of head 55 and plate 56 and is passed from thence beneath said finger and around wheel 44 which is projected through gap 35 to the position shown in Fig. 12. Wire 45 passes from thence back through gap 35 around an idler 62 to the supply roll 63 which is mounted on a suitable pin 64 011 the side of the hopper and is subject to the resistance offered by a compression spring 65.

With the parts in the position shown in Fi 19 late 42 is drawn back throu h "a i 35, by a mechanism which will be. described, until wheel 44 occupies the position shown in dotted lines at the left of Fig. 12, this movement passing wire 45 over the top of finger A of head 55, through notches 61, and 53, and between two of the cutters of head 52, the wire being looped around wheel 46, as shown in Fig. 20. This movement stretches wire 45 across the mouth of guide The material to be baled is deposited in hopper 31 and successive quantities are driven by packer head 33 through thehoper a ainst wires 45 and into uide 32 the wires 45 being tliusdrawn from rolls 63 into the guides 32 so as to be wrapped around three sides of the bale, as indicated in Fig. 12. i

As the to contact with a toothed wheel 7 O, which is projected into the bottom of guide 32 and is carried by a shaft 71, which carries a sprocket wheel 72 over which is passed a chain 73. Chain 73 extends over a timing sprocket wheel 74 which carries a cam 75 and when the bale 76 has advanced sufficient ly, this cam comes into contact with a latch 77 which is normally hooked into the eye of a plate 78 and yieldingly held in that position by a spring 79 (Fig. 1). As soon as the cam 75 shifts catch 77, the spring 80 acts v upon latch 77 to retract it through plate 78 so as to swing the bell crank lever 81 to the position shown in Fig. 5, thus lifting yoke 82. The yoke 82 (Fig. 2) forms a support for the free end of a finger 83 which is pivoted at 84 to a lever 85 connected at 86 to the packer head 33 and this finger carries at its free end a pin 87 which normally misses the adjacent end of lever 88 but, when raised, as described, comes into contact with the shoulder 89 of said lever 88 so as to swing said lever to the position shown in dotted lines in Fig. 2.

WVhen lever 88 swings to the position shown in dotted lines in Fig. 2, it swings lever 90 to the position shown in Fig. 6 and thus withdraws stop finger 911from in front of a finger 92 carried by a clutch member 93 journaled upon the constantly movbale progresses in size it comes ining shaft 94 and also withdraws pin 95' from a notch in a collar 96 carried by crank shaft 97. Lever 90 is normally ur 'ed to the position shown in Fig. 6 by a spring 98.

The finger 92, and the clutch of which it forms apart, is similar to the clutch shown in Figs. 8 and 9, which will be described later,and when lever 90 is shifted, as described, the clutch member 93, through finger 92, becomes connected withthe clutch 'member 99 carried by shaft 94 so that gear 100, operating through gear 101, shaft 102,

and gearsl103 and 104, rotates crank shaftnotches 53,- 60 and 61, as indicated in Fig. 16. hen the plate 42 is projected to. the position shown in Fig. 12, a finger 108 (Fig.7)

carried by said plate strikes alever 109 carried by a rock shaft '110 and operates through arm 111 to move bar 112 (Figs. 7

and 11) downwardly, so as to bring fingers 113 down upon the two portions of wire 45, down upon the tinger114 of the twisting mechanism (Fig. 13) and when this occurs,

a cam 115 on crank shaft 97, engages an arm 116 which pulls down upon bar 117.

Connected to bar 117 are ratchet arms 118, carrying a pawls 119, which act upon ratchets 12, carried by shafts 51, (Fig; 18) so that said shafts, with cutters 52 and retainer heads 55, are advanced of a rotation. Practically simultaneously with this move ment, a cam 130, on shaft 97, engages a lever 131 which carries two links 132. and Link 132 is connected to link 133 which in turn is connected to arms 134 carried by rock shaft-s 135, one for each twister meche anism, and these rock shafts carry arms 136 which are connected by links 137 with a cross head 138, said cross head being moved to the right from-the position shown in Fig. 10, so as to shift shafts 139 of the twister mechanism axially.

finger which lies in a spiral groove 141 in the tubular holder 142, so that, as these siafts 139 are shifted axially, they are also rotated so as to bring the pin 143 of each finger 114 first into the position shown in full lines in Fig. 13, and then into the position shown in dotted lines in'said figure, so as to put a kink in the two portions of the wire 45 just before one of the cutter fingers of cutter 52 cuts the two wires over the edge of plate 54 at notch 53. One of the regular shafts carries an arm 144 which is connected by link 145 and lever 146 with a bar 147 which is projected to the position shown in Fig.

13,- so as to formabutment- :for the two wires 15 and holdrtheniin the position.indi-.. cated in Fig. 13-, so that those. portions-man est the bale will be out-oi the pathot move mentiof thesevered ends of wire 41-5 when they are engaged and swung by 1116 131112149, carried bythe twister gear 150;

Link 154 isconnected by a lever 155 with. a stop finger 156 which:liesnormally in po.-. sition to engage and restrain a catch finger 157 (-likecatch finger 92). The catch finger 157 is pivoted at 158 on the clutch :i'nember 159- car ied 'by a sprocket wheel 16l): jour-. naled on the constantlysnoring shaft: 1.61 which is connected gears 162-and 163 with'shatt 941- and this catch-finger15'? is; provided with alateral projection-164 which, when the; finger is restrained bf/111% stop finger 156,- is held, against the actionot spring 165, out of the path of movement of a series of pins 166 carriedbya clutch memher 167 mounted on shaft 161, the arrangement being such thatwhen, andso long as, stop finger 156 is in the position shown-I in dotted lines in Fig. 8, the lateral projection 16% will'be engaged by one or another of pins 166 and sprocket wheel 160 will be rotated by shaft 161. Sprocket wheel 160 (Figs. 7 and 10) is connected by achain 168 with a sprocket wheel 169 carried by a shaft 170 of an idler gear 171 which meshes with one of the twister gears150 and with an idler gear 172 which meshes with an idler gear 173 meshing with theother twister gear 150, the arrangement being-such that rotation of the sprocket wheel 160- will produde rotation of the twister gears 150 so as to wrap the free ends of the wire 15 around said wires, as indicated in Fig. 15',soas to tie the two wires together.

Cam 7 5 promptly passes latch 77 and the co-action between finger 83and lever 88 draws yoke 82 downwardly against the action of spring 80, returning said yoke 82-andlatch W'to: normal position, and as cams 115 and 130 promptly pass their respective levers 116 and 131, and as pin 95 rides upon the circumference of disk 6, it is apparent that, upon a complete rotation of crank shaft 97*, the two, clutches 9399* and 160- 167 will be automatically dissociated and when pin 95. drops into the notch of disk 96, the yarious parts are thus restoredto normal inactive position, ready tcrtanother operation when the parts reach the position shown in Fig. 7. i

The projection of wire 15 across the fourth side of the bale and the tying of the ends of the wiretogether by the loop shown in Fig. 15 takes, place during a return stroke of the packer head 33 to the position shown in Fig. 1. lllheQadvancement of shafts 51,'brings one thefingersot cutter 52 into position to sever the wires 45, as already described,

and then brings; one ofthefingers (say A) of: the hold-er intoengageinent, witlrsa d;
